You soldered the wire in as opposed to soldering onto the wire and using the screw to attach to a 'blob' of solder. The Xhadow plugs are designed so you don't have to solder!
You never sent back the $60 plug to USA Hifi
You never took the time to clarify your understanding the project. I sent phono clips and litz wire, you made an XLR cable (granted they did mail you 1m, and 1f plug so I'll let the slide, sort of).
You never responded after multiple shipping labels were sent to you in the hope you would send back the expensive other cables I sent you to evaluate , which I needed to sell.
You never responded after months when I asked you to just let me finish the project.
